The ``ads1115`` domain creates a global hub so that you can later create
|
|
individual sensors using the :doc:`ADS1115 Sensor Platform </components/sensor/ads1115>`.
|
|
To use this hub, first setup the :ref:`I²C Bus <i2c>` and connect the sensor to the pins specified there.

Configuration variables:
|
|
------------------------
|
|
|
|
- **address** (**Required**, int): The i²c address of the sensor.
|
|
See :ref:`I²C Addresses <ads1115_i2c_addresses>` for more information.
|
|
- **id** (*Optional*, :ref:`config-id`): Manually specify the ID for this ADS1115 Hub. Use this if you
|
|
want to use multiple ADS1115 hubs at once.

I²C Addresses
|
|
-------------
|
|
|
|
In order to allow multiple sensors to be connected to the same i²c bus,
|
|
the creators of this sensor hardware have included some options to
|
|
change the i²c address.
|
|
|
|
- If the address pin is pulled to GND, the address is ``0x48`` (Default).
|
|
- If the address pin is pulled to VCC, the address is ``0x49``.
|
|
- If the address pin is tied to SDA, the address is ``0x4a``.
|
|
- If the address pin is tied to SCL, the address is ``0x4B``.
